Vascular surgery
About 35361: Aortic thromboendarterectomy
Open aortic thromboendarterectomy removes obstructive plaque from the aorta to restore blood flow, with patch grafting included when performed.
A vascular surgeon uses this code for open removal of obstructive atherosclerotic material from the aorta to improve its channel for blood flow. A patch graft may be used to repair or enlarge the vessel after plaque removal and is included in the service. The procedure is generally performed in an operating room, commonly in a hospital facility, for significant aortic occlusive disease requiring surgical treatment.
Select this code when the treated artery is the aorta; an aortoiliac procedure or endarterectomy of another named artery belongs to a different code. The operative report should identify the aorta as the treatment site and document plaque removal and any patch repair. This is major surgery with a 90-day global period, including the day-before preoperative visit and related postoperative care for 90 days. When multiple procedures are performed in the same session, the highest-valued is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
